It is our designated intention [https://sfconservancy.org/news/2020/jun/23/gitbranchname/] to "to explore changing the name of the first branch created automatically for new repositories away from ‘master’". Further, we promised that we "will minimize disruption for Git's users and will include appropriate deprecation periods". To that end, we first clarify git init's documentation (a lightly edited version of Junio's patch [https://lore.kernel.org/git/xmqqd00a36wc.fsf@xxxxxxxxxxxxxxxxxxxxxx]), and then introduce a message giving advice to users running git init that the fall-back for init.defaultBranch is subject to change, and how to override Git's fall-back manually. The beauty of this patch series, if I may say so, is that it does not commit us to any concrete plan, but opens the door for all options regarding the default branch name. Changes since v4: * Reworded the documentation to weaken the "will be changed in the future" to "is subject to change". * Reworded the advice to explicitly mention "instead of 'master'". Changes since v3: * Kicked out advice.defaultBranchName again. The advice can now only be suppressed by setting init.defaultBranch. Changes since v2: * git branch -m <initial> <renamed> now works, too * The config setting advice.defaultBranchName was introduced to allow suppressing this warning specifically * The advice now first talks about the current default branch name, then how to suppress the advice, and only then explains how to override the default branch name (and that that will also prevent the message from being shown) Changes since v1: * Grammar fix * Reworded advice and commit messages * test_create_repo already respected GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME, but now does so more obviously * Allowed git branch -m <name> to rename unborn branches, so that the advice actually works Johannes Schindelin (4): init: document `init.defaultBranch` better branch -m: allow renaming a yet-unborn branch get_default_branch_name(): prepare for showing some advice init: provide useful advice about init.defaultBranch Documentation/git-init.txt | 11 +++++++---- builtin/branch.c | 4 +++- builtin/clone.c | 2 +- builtin/init-db.c | 8 +++++--- refs.c | 24 ++++++++++++++++++++---- refs.h | 4 ++-- remote.c | 5 +++-- t/t0001-init.sh | 17 ++++++++++++++++- t/t1510-repo-setup.sh | 2 +- t/test-lib-functions.sh | 4 +++- 10 files changed, 61 insertions(+), 20 deletions(-) base-commit: faefdd61ec7c7f6f3c8c9907891465ac9a2a1475 Published-As: https://github.com/gitgitgadget/git/releases/tag/pr-git-921%2Fdscho%2Finit.defaultBranch-advice-v5 Fetch-It-Via: git fetch https://github.com/gitgitgadget/git pr-git-921/dscho/init.defaultBranch-advice-v5 Pull-Request: https://github.com/git/git/pull/921 Range-diff vs v4: 1: 483e4903491 ! 1: ce35cf3da65 init: document `init.defaultBranch` better @@ Documentation/git-init.txt: If this is reinitialization, the repository will be -If not specified, fall back to the default name: `master`. +Use the specified name for the initial branch in the newly created +repository.
